BACKGROUND

1. Technical Field

The disclosure generally relates to electronic devices, and particularly to an electronic device with a spray type heat dissipation.

2. Description of Related Art

Heat dissipation devices, such as a fan and a heat sink are located in an enclosure of an electronic device for dissipating heat. Power consumption and heat from the electronic device increase with the enhancement of performance For satisfying increased heat dissipation demand, a fan with better heat dissipation effect, such as higher rotation speed, or larger blades is required. Fan with higher rotation speed may generate greater noise, and the enclosure of the electronic device has to be enlarged if larger fan is used. Thus, there is a room for improvement within the art.

The buffering pipe 551 connects the outlet pipe 533 of the pump member 53. The outlet pipe 533 engages with the buffering pipe 551 by an interference fit. The buffering pipe 551 is substantially U-shaped for preventing water backflow. The spray pipe 555 and the connecting pipe 553 are substantially straight. The spray pipe 555 is substantially perpendicular to the connecting pipe 553. The spray pipe 555 and the connecting pipe 553 are located in a first plane. The buffering pipe 551 is located in a second plane. The first plane is substantially perpendicular to the second plane. A plurality of nozzles 556 is defined in the spray pipe 555. The plurality of nozzles 556 is evenly spaced.

FIG. 5 illustrates a partially assembled view of the electronic device 100. The heat sink 30 is located on the motherboard 20. The first end of the heat pipe 35 contacts the plurality of elements 23, and the second end of the heat pipe 35 contacts the plurality of fins 34. The plurality of fins 34 is located between the fan 31 and the outlet 124 of the enclosure 10. The press cylinder 532 is mounted to the water box 51. The inlet pipe 531 extends into the water box 51. The cap 537 is attached to the press pole 535. The baffle 58 is mounted to the opening 22 of the enclosure 10.
